Your backyard hangs, basement afters, and all-night ragers will never be the same. The JBL PartyBox 330 brings deep, punchy bass and crisp highs with a wide soundstage — powered by 280W RMS, dual 6.5″ woofers, and twin 25mm PEN dome tweeters. AI Sound Boost and Smart EQ keep sound big, loud, and clear even when you go full throttle.
An adaptive futuristic lightshow (ripple light trails + strobe edge lights) syncs to your music. A redesigned top panel gives fast access to audio and light effects. Roll it anywhere with a telescopic locking handle and wide sturdy wheels. Up to ~18 hours playtime, Fast Charge (about 10 minutes ≈ 2 hours), and a replaceable JBL Battery 400 keep the party going. IPX4 splash-proof.
Plug in dual mics and a guitar for live sets. Connect via USB-C lossless, optical, or 3.5mm aux. Pair more speakers with Auracast™ (Bluetooth 6.0) and control everything from the JBL One app. Compatible with JBL EasySing mics. Available in Black or White.
